Only if you plan to use 4 chanels at 100MHz BW signal. If using 2 channels the rigol has 500MSa/s which should be enough for a 100MHz signal, so still useful there but only using 2 channels. While the siglent using 2 channels you can get 1GSa/s, and using only one channel both 1GSa/s.
I went for the Rigol because was waaay cheaper to get for me, I would have to pay twice to get the Signlent, as shipping rates from stores where it was available to ship to me were way higher, like 3 times what I payed for the Rigol shipping. YMMV here, so with a closer price the fight is open. Then there are a few other differences, the bode plotting looks great, probably better with a dedicated signal generator than the optional one for the scope, but still not great as it has many limitations. The ability to add the logic analyzer later is a nice one too, for having a MSO as the time comes, and money and needs agreed on this, but is an expensive option to have a logic analyzer compared to many other out there, and going to the PC as usual as I do I can mix them there (analog and digital) for the time where it's needed)

For my current needs, they're both overkill. The issue is that people keep giving me ideas of how I might use them, and some of them sound reasonable. For me, the difference in price will be about $140 between the two units, and I get free shipping.
In all honesty, being the tech/computer type that I am, it bothers me to pay for an old computer. From that perspective, and for an extra $140 I get a newer computer with 1M FFT, double the multi-channel sampling, built-in web server, 400VDC input, and the POTENTIAL for other crap I
probably won't use. I probably won't ever use the logic input, but it's there. I dunno if I'd ever shell out any cash for their AWG addon, but the option is there.
And even though I don't care at all about the WiFi module, I'm interested in it for one reason: the TP-Link adapter model (TL-WN725N) that Siglent charges $70 for is available for $10 or less, and I'm curious if I could get the cheap one to work. I dunno if anybody has tried or not, I haven't looked yet.
Thanks,
